It just looks like a weird bump. Pics really won't show anything that's going to jump out at you with an answer. Obviously, I know from experience that when a muscle tears, it bleeds. I thought for sure that's what happened to him, but he said there was absolutely no bruising? His chiropracter said it was definately a tear, so who knows. I know Eric is all over sports injuries, so I told Shaver to post a thread since I know he'll figure it out better than I could.
At least this could give him an idea to what it is.
